The RKB NUB series cylindrical roller bearing is a high radial capacity component, designed to withstand heavy loads and moderate speeds in industrial equipment. Its cylindrical roller design provides linear contact that distributes the load over a wide surface, resulting in rigidity and durability. It is used in applications where precision and fatigue resistance are critical, such as heavy machinery, gearboxes and continuous process equipment.

The NUB series designation can be read from its structure: the letters identify the bearing type and its design features, while the numbers that follow indicate the size or specific variant. For example, NUB 18/1000 corresponds to a large-diameter version, while NUB 312961 and NUB 313638 are catalogue references for particular applications. Each suffix or numeric combination corresponds to a different internal design, so it is essential to use the complete part number when making an enquiry.

These bearings are used in industries such as steel, cement, mining and in food and beverage processing plants. In Argentina, they are commonly found in gearboxes, conveyor belts, mills, presses and material handling equipment. Their ability to withstand high radial loads and their fatigue resistance make them suitable for continuous duty cycles, where reliability and component service life are decisive factors in avoiding unplanned downtime.

To correctly select an NUB bearing, take into account the radial load, the rotational speed and the environmental conditions. It is important to verify the required sealing type: open, with shields or with seals, depending on the presence of dust, moisture or particles. Lubrication must be suitable for the operating temperature, and mounting requires precise alignment between shaft and housing to avoid additional stresses. Incorrect fitting can reduce bearing service life and affect equipment performance.

Regarding equivalences and interchangeability, cylindrical roller bearings from different brands may share standardized dimensions, but commercial designations vary. If you need to replace a bearing from another brand, the safest approach is to compare the main dimensions and load conditions. With the exact part number or dimensions, at MR Accesorios Industriales we can indicate the compatible alternative or provide a quote for the part number you need.

To proceed with a quote, send us via WhatsApp the complete part number of the RKB NUB series bearing you are looking for, or the dimensions and characteristics of the original part. At MR Accesorios Industriales we will reply shortly with the information you need to evaluate its installation in your equipment. We can also advise you on the appropriate lubrication and mounting to maximize the component's service life.

Frequently Asked Questions

What does the NUB designation mean in RKB bearings?
The NUB designation identifies a series of cylindrical roller bearings with specific design features. The numbers that follow indicate the size or variant. To correctly interpret a part number such as NUB 312961, you need to consult the manufacturer's catalogue or contact us with the complete part number.
How do I choose the right NUB bearing for my application?
You should consider the radial load, speed, sealing type and environmental conditions. It is also key to verify the shaft and housing dimensions. With that data, we can guide you in selecting the correct part number or a compatible alternative.
What care does the mounting of a cylindrical roller bearing require?
Mounting must be carried out with precise alignment, cleanliness and adequate lubrication. Avoid direct blows on the rollers and verify the internal clearance. Incorrect mounting can cause premature failures. If you have any doubts, contact us on WhatsApp.
